Hello,I am using a STM32H743ZIT6 in a custom PCB, the MCU and reference voltage at 3.3VOur intention is to use the built-in ADC to read some DC signals. One signal is our 24V power rail. In our circuit, nominal 24V is scaled down to 1.643V through a ...
We are working on a design that includes an STM32U545 running at around 1MHz to save battery power for the overall board. We have a requirement to write to an event log when the power is removed (this is the main operating power, not VBAT).The softw...
Hi,I am having Nucleo 476RG board.I configure Alarm A. HAL_RTC_AlarmAEventCallback functions is called upon occurrence of Alarm.Now when I configure AlarmA and then enter standby mode, the board wakes up from the standby mode upon the occurrence of a...
Hello. I have LIS3DH accelerometer and I would like to use it with my ST32F4 board.I have found the BSP drivers :STM32Cube\Repository\STM32Cube_FW_F4_V1.28.0\Drivers\BSP\Components\lis3dshand also available here:https://github.com/STMicroelectronics/...
I cannot enter the bootloader with the BOOT0 pin in the STM32G0C1 while I can with the NUCLEO-G0B1RE.I already checked the option bytes, and tried with nBOOT_SEL = 0 and nBOOT_SEL = 1.In the Nucleo board, it seems this nBOOT_SEL has no effect at all,...
Hello,I have two stm32f411e-disco cards. I want to synchronize the clocks of these cards. In other words, I want the clock of one of them to run synchronously with the clock in the other stm. How can I follow a way. As an example, I can say the follo...
Hello,I am new to STM32 and would appreciate your help in selecting a suitable MCU from the STM32 series for our project.We require the following features:- MCU with Wi-Fi, BLE, and GSM capabilities.- GSM integration via UART, with library support f...
Hi everyone, long story short is that i'm trying to use the system bootloader capabilities to handle updates over UART which open the possibility of OTA and everything goes smoothly until i need to write the new data, i've been pulling my hair off fo...
Hello,I am using RTC internal wake [10 sec] using the following code:void go_to_sleep(void) { HAL_SuspendTick(); HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 10, RTC_WAKEUPCLOCK_CK_SPRE_16BITS); HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI); HAL_RTCEx_Deact...
Hello.In STM32H7S7L8HXH_flash_default_app.ld, it is set to __FLASH_BEGIN = 0x08000000,In STM32H7S7L8HXH_RAMxspi1_ROMxspi2_app.ld, it is set to __FLASH_BEGIN = 0x70000000.In fact, 0x08000000 is not uploaded, and 0x70000000 is uploaded and works.Can I ...
